How to check if ref. S5720200 is the part for your boiler

What determines it is not the boiler model, but the reference printed on the part you already have installed.

1. Find the reference printed on the installed part and check whether it matches the catalogue reference S5720200. If it is not visible, do not identify the part from its shape alone.
2. Check the full boiler model on its data plate and look for it in the model associations on this page.
3. Compare the connections and physical body with the original part before installation.
4. If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.

Symptoms and faults that the flow meter S5720200 resolves.

The flow meter detects the passage of water to activate the domestic hot water. These are the typical symptoms and what to do:

Common symptoms and faults

• 01

  Dripping or moisture notes in the area of the flow sensor.

  Cause: The flow detector is made of plastic and can break due to pressure or impact.

  Dry the area, wait a few hours, and check if the moisture reappears on the sensor.

• 02

  When turning on the hot water tap, the boiler does not ignite and remains cold.

  Cause: If the detector does not activate the flow, the boiler does not receive the signal to turn on.

  Before changing the sensor, make sure there is normal flow and that the inlet filter is not blocked.

• 03

  The boiler does not prioritize domestic hot water while the heating is running.

  Cause: A flow detector that does not measure the domestic hot water consumption correctly prevents the boiler from managing the priority.

  Check in the boiler menu that the domestic hot water priority function is activated.

• 04

  A warning appears on the screen related to the domestic hot water circuit when the tap is opened.

  Cause: The boiler detects erratic signals from the sensor as a fault in the domestic hot water circuit.

  Note the code that appears and compare it with the manual before considering that the detector is faulty.

These symptoms can have more than one cause. If your boiler displays a fault code, send it to us via WhatsApp along with a photo of the labeling, and we'll tell you if this is the part.
